You can, but...

Doe is unrelenting as her pussy squishes and squelches over your rod. You feel the combination of the creampie you flooded her with and her ample flowing juices run down over your thighs, coating your balls, ass, and soaking your sheets. It's going to smell like two horny teenagers fucking in here for months.

Good. And if anything, that just made your cock harder, stretching a tiny bit wider and deeper in Doe. She's riding you with everything she's got, and you're surprised the bed isn't squeaking with the effort. It's insane how tight she is given how wet her soaked snatch is, and it feels like she's trying to milk you deeper and stretch you longer with each piston of her hips.

With the fresh load of jizz already boiling in your creampie-and-pussy-soaked balls, you think about anything you can to keep from blowing until Kammy shows up. Your hands fly to Doe's hips to try to slow her down and control her motions a bit, which makes her moan a protest, but kicks the heat up in her pussy as her body reacts to you taking control.

"Fuck, John," she moans, adding a grinding spin to her motions. "Fuck....Julie's going to love this..."

Your body betrayed you at the mention of your sister's name and your dick got even harder in her friend.

"Kammy, you mean?" you corrected, panting with the effort of not cumming

"Sure, sure....both. I felt that dick twitch!" she hissed. "I meant Kammy...but...mmm....your sister is just fucking delicious..."

You felt the pressure and heat in your balls rise with the need to cum, but you wanted to wait...

"God, those tits. Have you seen them?" Doe struggled to say between sloppy wet slapping pounds of her clit. You could feel your balls bouncing up with the impact. You've seen your sister's tits before. You've seen all of her before coming out of the shower. You've seen the nest of pussy fur between her thighs, the flash of pink. You've jerked off to her more than once, and this slippery cunt driving up and down on your shaft is in dire need of another flooding.

You look to your alarm clock, it's only been five minutes....

"And that pussy...tight as mine...just as juicy...fuck does she taste good..." Doe taunts. Fuck you want to cum. And you realize, you don't just want to cum in Doe's womb, but your sister's, Mary's...and fuck, if fucking your sister is on the table, pretty much every woman is...

"Don't cum in me yet....don't think about cumming in your sister while fucking me..." Doe gasped.
